Problem, 1450--(Maze-High level) 1: Introduction Problem description and (ifany) background of the algorithms. n*m,sT,( )(,, ) Given an m Maze, the starting point S and the ending point T. find a shortest) path from S to T for for simplicity, it is OK to just find a path from S to T) Tips:use a stack to store the position aleady detected Input 1:n ; 2. (n+1):m, , "9" , . ". Linel: two integers n and m, Lines 2-(n+1): m elements in each line, to describe he maze: where-S' and T' denote the starting point and the ending point, respectively: -#, denotes blocked, cannot pass here" and denotes "pass here" Output s, At least, how, many steps can a robot reach to Tfrom-S'. and output this number: if no way, then output -1 (: , Alternative simpler ome: just finding a path from the starting point S" to the ending point T, not required the shortest one) Sample Input S. Sample Output 2: Algorithm Specification Description (pseudo-code prferred) of all the algoritkms involved for solving the problem, including specifications of main data structures 3: Testing Results Table of test cases. Each test case usually consists of a brief description of the purpose of this case, the expected result, the actual behavior of your program, the possible cause of a bug if your program does not fiunction as expected, and the current statuspass". or "corrected". or pending 4: Analvsis and Comments Analysis of the time and space complexities of the algorithms. Comments on further possible improvements. Time complexities: Appendix: Source Code (in C/C+) At least 30% of the lines must be commented Otherwise the code will NOT be evaluate
